It is well known that water and asphalt will not mix, except under carefully controlled conditions using highly specialized equipment and chemical additives.
. IT is one of the stones that shows great resistance to heat. This stone weighs about 2560 kg per square meter and its compressive strength and reliability are higher than travertine and lower than granite. marble has a wide range of colors due to the presence of impurities within. This stone can be used as flooring and wall covering.
